what is evidence based practice?
encompasses empirically supported tx but not equivalent
the 3 legged stool
what are the 3 legs of evidence based practice?
- best evidence from research
- clinical expertise
- patient preferences
3 legs of EBP
what’s the best scientific evidence?
results from experiments and quantitative studies
3 legs of EBP
what is clinical expertise?
3 elements
competence attained by psychologists through education, training, experience, that result in effective tx
* expert panels
* practice groups
* consensus statements
3 legs of EBP
what’s patient preference?
4 elements

what are the 6 levels of research evidence
it’s a pyramid!

- case-control studies
- case series, case reports
- editorials, expert opinion
what is efficacy?
performance of an intervention under ideal and controlled circumstances
maximizing internal validity, ruling out confounds
what is effectiveness?
how well the tx works among gen pop
generalizability
leg 1: research evidence
what are the sources of evidence of the first leg?
3
- efficacy
- effectiveness
- basic psychological processes relevant to tx
what are some issues with effectiveness when studying therapies in clinical settings?
there are 5 i can think of
- academic settings are usually sterile
- possible allegiance effect
- administered by people who designed the study
- highly trained therapists with advanced degrees
- voluntary bias: types of people who volunteer to do these experiments aren’t representatitve of gen pop
limits generalizability of findings
what is dissemination research?
research that focuses on tx effectiveness testing in real world settings

- patient diversity
- mode of delivery
- feasibility of delivery irl
- tx costs
- therapeutic relationships
